How to export a 2D stabilized movie clip?
After setting up and tracking a video in the movie clip editor, you will want to use the tracking data to export an altered video. The adjusted video you see in the clip editor is only an in-memory adjusted version for feedback purposes.

To get a final adjusted video output you will need to setup some compositing nodes to adjust the "rendered" output. The minimum setup you will want is a movie clip input node, a 2D stabilization node and a composite node, a viewer node will let you preview the result behind the nodes if you enable the backdrop option.



Of course you can also add any other nodes to this for colour correction or adding 3D objects etc.

Now when you press render the result will match what is connected to the composite node.
